The styrene gas that leaked from LG Polymers on 7th May 2020 has killed many in Visakhapatnam

Styrene, also known as ethenylbenzene, vinylbenzene, and phenylethene, is the precursor to polystyrene and several copolymers. Approximately 35 million tonnes of styrene was produced in 2018.

Styrene is regarded as a known carcinogen, especially in case of eye contact, but also in case of skin contact, of ingestion and of inhalation. Styrene is metabolized into styrene oxide in humans and is considered toxic, mutagenic, and possibly carcinogenic.
